Parenchyma is a type of simple plant tissue composed of thin-walled cells with large central vacuoles and living protoplasts. Parenchyma cells are versatile and can perform a wide range of functions in plants. Some of the key characteristics and functions of parenchyma cells include: Storage: Parenchyma cells can store various substances, such as starch, oils, proteins, and water, depending on their location in the plant. For example, parenchyma cells in storage organs like roots, stems, and leaves can store starch and other nutrients. Secretion: Some specialized parenchyma cells, called secretory cells, can secrete substances such as resins, latex, and nectar, which can have defensive or protective functions in plants. Photosynthesis: Parenchyma cells in the mesophyll tissue of leaves can contain chloroplasts and perform photosynthesis, playing a crucial role in the process of producing energy for the plant. Intercellular spaces: Parenchyma cells often have intercellular spaces between them, which can be schizogenous (formed by cell separation) or aerenchymatous (formed by cell dissolution), allowing for gas exchange and facilitating processes such as respiration and fermentation. Universal tissue: Parenchyma is a widespread and common type of plant tissue that can be found in almost all parts of the plant body, including roots, stems, leaves, flowers, and fruits. Hence, parenchyma is often referred to as 'universal tissue' due to its ubiquitous presence in plants.
